Nintendo reboots with new Switch game console

Nintendo has unveiled its new Switch game console, which works both at home and on-the-go, as it tries to offset disappointing Wii U sales and compete with Sony's big-selling PlayStation 4.

The hybrid device - which goes on sale March 3 for US$299.99 (A$400) - comes as Nintendo also dips its toe into the mobile gaming market following its big brand win after Pokemon Go's worldwide success.

At a Tokyo media briefing, the company said the console is packed full of Nintendo's "entertainment DNA", taking elements of earlier devices including the 3DS handheld and motion-sensor Wii.

Switch got off to an inauspicious start in October when a sneak peak at the console left gamers and analysts underwhelmed and with many unanswered questions.

Friday's launch is "a key turning point for Nintendo's earnings and share price", Daiwa Securities said before the event.

But Nintendo's Tokyo-listed stock dived after it released a three-minute video about the product on YouTube.

Switch has a removable screen that lets players dock it at home and also use it on the go like a tablet computer with detachable controllers - called Joy-Con - on both sides. It uses cartridges rather than discs.

The idea is to give users a more immersive experience with realistic physical sensations matched to what is happening on-screen, the firm said.

A remote control feature means players don't always have to keep their eyes on screen while punching the air in a boxing game or getting into a gun duel.

Only eight games will be available when the system goes on sale in March including a Legend of Zelda offering. But there are some 80 more games in the pipeline, Nintendo said.

Similar briefings are being held in Paris, London, Frankfurt and New York.

Switch will be crucial for Nintendo, which needs a hit product to offset the flagging fortunes of the Wii U and 3DS, as rival Sony racks up huge sales of the PS4 - it has sold more than 50 million units globally since its debut in late 2013.

In November, Sony started selling the US$400 (A$533) PS4 Pro, which promises even sharper graphics than earlier versions.

Switch underscores how Nintendo tends to look at gaming as fun play while Sony's big focus has been on visuals, gaming specialist Hirokazu Hamamura said.

"It's a Nintendo-esque game console that shows how the company sees gaming as 'play' rather than image arts," Mr Hamamura told AFP at the event.

After struggling to fix its weak finances, Nintendo abandoned a long-held consoles-only policy and decided to enter the smartphone game market.

Last year, the Super Mario and Donkey Kong maker released "Miitomo" - a free-to-play and interactive game - as it tries to compete in an industry that has increasingly gone online.

It scored another hit with the Pokemon Go app released in July, but the impact on Nintendo's profits will be limited.

The company is the creator of the Pokemon franchise but does not own the licence for the game, which was developed and distributed by US-based Niantic, a spinoff of Google.

Last month, Nintendo released the Super Mario Run game for iPhones, which topped download charts and drew more than 40 million downloads globally in the first four days after its release, according to the company.

But analysts warned its popularity could be hampered by a relatively high $10 price tag for access to the full game, since many online offerings are free.
